AdlibRegister passes global variable instead of using default parameter?

[Ontosy]

I’m seeing unexpected behavior when using AdlibRegister with a function that has a default parameter.

Example:

Local $a = "Alx"
AdlibRegister("KeyboardShow", 1000)
Sleep(5000)

Func KeyboardShow($a = True)
    ConsoleWrite("[$a] = " & $a & @CRLF)
EndFunc

When KeyboardShow is triggered by AdlibRegister, it prints "Alx" — even though no parameter is passed, and the default is True.

Why is it picking up the global $a instead of using the default?

In most other languages, the function parameter would shadow the global variable, and the default would apply when no argument is passed.
But in AutoIt, it seems like the global variable is used instead — is this expected behavior, or a quirk to avoid?

Hi. AutoIt help file, topic AdlibRegister

You can not register a function using parameters.

Does this answer your question ?

I know this but if register not pass parameter function then parameter have to be default True or not declared and not global value.

Any other language this do. Autoit3 is border line?

What about this ?

Global $a = "Alx" ; comment out this line to see a different output
AdlibRegister("KeyboardShow", 1000)
Sleep(5000)

Func KeyboardShow()
    If Not IsDeclared("a") Then $a = True
    ConsoleWrite("[$a] = " & $a & @CRLF)
EndFunc

Autoit3 should handle and isolate parameter in function how other languages commonly do.

..take a look at this chunk of code, maybe that will work for you ?
The part of:

If Int(Execute("$iInit")) == 0 Then

you not have a $init at parent level.

Yes, is the 1st parameter that on a regular Function call, is there, but under OnAutoItExitRegister() or Adlib in your case, none of these parameters exist so, that shows how I got creative with it.

I not search a work around but evidence limites.

@Ontosy, this is Sparta, I mean, this is AutoIt. If you rather use languages that have those, use those 🤔
